Micro mechanics of the critical state line at high stressesTools de Bono, John P. and McDowell, Glenn R. (2018) Micro mechanics of the critical state line at high stresses.

A previous theory for the normal compression line, which correctly predicts the slope as a function of the size-effect on particle strength is extended to justify the slope of the critical state line. The micro mechanics behind critical states are examined, leading to a theory for a relationship between the volume of smallest particles and mean effective stress. A unique relationship exists for crushed states, leading to a two-dimensional interpretation of the state boundary surface for soils looser than critical.
